Growth Stages

1

Establishment

6-12 months

Young plant with fine needle-like foliage beginning to form a mounded shape. Growth is slow and steady.

Water regularly to establish deep root system. Apply 2-3 inches of mulch around base. Protect from harsh winds in first year. Avoid waterlogging.

2

Vegetative Growth

1-2 years

Plant develops dense branching structure with increasingly fine foliage. Overall shape becomes more compact and mounded.

Light pruning to maintain shape can be done in spring. Reduce watering frequency as plant matures. No fertilizer needed if soil is adequate; avoid high-nitrogen feeds.

3

Flowering

4-6 weeks

Small, fragrant white or pale yellow flowers appear among the foliage, typically in late spring to early summer. Flowers are inconspicuous but aromatic.

Do not deadhead if fruit formation is desired. Maintain consistent (but minimal) watering during bloom period. Light pruning after flowering maintains shape.

4

Fruiting & Maturity

6+ months of berry display

Small dark berries (drupes) form after flowering, persisting through fall and winter, providing ornamental and wildlife value. Plant reaches full mature size.

Minimal maintenance required. Prune only to maintain desired shape or remove dead wood. Occasional deep watering during drought stress. Berries attract birds.
